tardive dyskinesia

The US Food and Drug Administration has approved an 80 mg capsule dose of valbenazine (Ingrezza) for tardive dyskinesia (jerky, involuntary movements of the face, especially the mouth and tongue, fingers and body that can be a side effect of antipsychotic medication). Valbenazine, a selective vesicular monoamine transporter 2 inhibitor, was the first drug FDA-approved for tardive dyskinesia. The FDA initially approved a dosage of 40 mg/day in April 2017. The 80 mg/day dose was approved in October 2017.

The new approval was based on a 6-week clinical trial in which 80 mg of valbenazine improved tardive dyskinesia significantly compared to placebo. Improvement continued over 48 weeks of treatment.
